Socket, a blockchain interoperability protocol, disclosed a breach that resulted in a loss exceeding $3.3 million. The exploit, attributed to a flaw in user input validation, targeted wallets that had granted infinite approvals to Socket contracts. This vulnerability allowed unauthorized fund transfers, highlighting the critical importance of robust security measures in the evolving decentralized finance (DeFi) landscape.
Vulnerability Unveiled: The Exploited Flaw
Blockchain security firm PeckShield revealed that the security breach was linked to a specific route within the system, added just three days before the attack. This route, crucial to the Bungee bridging aggregator, had an input validation flaw that exposed the protocol to exploitation. Following the incident, Socket promptly deactivated the problematic route to prevent any further misuse.

Socket’s Response and Mitigation Measures
Socket responded promptly to the breach, acknowledging the vulnerability in user input validation. In an effort to mitigate the impact and safeguard user assets, the affected contracts were temporarily paused. Socket reassured its user base that no additional actions were required on its part, emphasizing the commitment to protecting the community’s interests.
Identifying the Root Cause
Hacken, a cybersecurity firm, confirmed that the vulnerability originated from a recently deployed contract. The flaw in user input validation allowed attackers to manipulate the contracts for unauthorized fund transfers. Socket’s vigilance in identifying and addressing the root cause underscores the ongoing challenges in maintaining smart contract security as DeFi platforms advance.
